FRANK DUTCI-IER, OF VERSAILLES, PENNSYLVANIA, ASSIGNQR TC CENTRAL RAILVJAY SIGNAL COMPANY, OF PITTSBURGH, PENNSYLVANIA, A C(IBIORATION OF NEW J EBSEY.

FIBER BAILVJAY SIGNAL-TORPEDO.

Application filed April 4, 1916.

To all whom it may concern Be it known that I, F RANK Dn'ronnn, a citiien of the United States, residing at Versailles, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fiber Railway Signal-lorpedoes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in fiber railway signal torpedoes, and it pertains to a torpedo of the non-flying type, that is to say, a torpedo which is constructed and the parts of its case held without the use of any metal securing means.

The present invention is especially adapted to be utilized in a torpedo of an essentially fiat and rectangular shaped case.

A further object of the present invention is to construct the case of the torpedo of inner and outer members, and to have the railengaging member or strap attached to or carried by the inner member.

A further object of the present invention is to construct the inner or explosive containing member of an elongated tube with the explosive in the middle thereof and the ends of the tube doubled back under the torpedo and preferably overlapping,

V whereby the doubling of the flattened tube closes the tube against the entrance of water therein to enter the explosive and thereby destroy or deteriorate its efliciency, and to provide a surrounding case or member which serves to hold the doubled ends of the container in their doubled or closed positions, and also to strengthen the case.

In the accompanying drawingFigure l is a perspective view of my improved torpedo, showing it of an elongated flat reetangular case. Fig.2 is a transverse sectional view through the center of Fig. 1. Fig. 3 is an inverted perspective view of the inner explosive containing case with the rail-engaging strap attached, and the outer case in dotted lines. Fig. 4 is a longitudinal central sectional view of my improved torpedo, showing a modification in the attachment of the rail-engaging strap. Fig. 5 is a perspective view of my improved torpedo shown of a substantially square rectangular fiat case, with the rail-engaging strap arranged at right-angles in respect to the explosive containing case, from that shown in Figs. 1, 2, 3 and 4:. Fig. 6 is a Specification of Letters Patent.

longitudinal central section through Fig. 5. Fig. 7 is an inverted perspective view of the inner or explosive containing case with the rail-engaging strap attached to the inner case, and the outer case shown in dotted lines. Fig. 8 is an inverted perspective view similar to Fig. 7, but showing a modification in the manner of attaching the railengaging strap. Fig. 9 is a longitudinal central sectional view of the completed torpedo having the rail-engaging strap at tached, as shown in Fig. 8.

In carrying out my present invention, I provide an inner explosive containing case 1, which is made from a flattened tube. This flattened tube has its ends 2 extending beyond the explosive 3, which explosive is preferably in the form of a tablet. These extended ends are flattened beyond the explosive, as shown in Fig. 3 and are doubled under the bottom of the case and preferably made of a length to overlap, as shown particularly in Fig. This inner explosive containing case 1, carries a rail-engaging strap i, and this rail-engaging strap, as shown in '2 and 3, is threaded through openings 5 made in the outer layer of the outer doubled back end 2. The threading of the strap 4'; through these openings will. bulge or force outward the wall of the tube somewhat as shown in Fig. 3. The flattened tube out of which the inner explosive containing case 1 is made, is composed of paper or other suitable fiber, so that there is no metal part in the explosive container to fly when the torpedo is exploded. The explosive containing case is inclosed within an outer case 6, which also is of a flattened tubular form with open ends 7 to permit the insertion of the explosive containing case 1 therein, and the outer case serves to hold the flattened doubled back ends 2 in their folded positions against the bottom of the case 1, as shown. The doubling back of the flattened ends 2 serve to make a waterproof inclosurc for the explosive and prevents the passage of water through the tube and into the explosive.

After the torpedo is assembled it is preferably dipped into a suitable waterproof compound or cement which will serve to make the case waterproof and to cement the inner and outer cases together. No attempt is made to show the waterproof cement and. in fact, it would not be practical to show it in the drawing, because it is of a transparent nature and preferably very thin, not any thicker than'a thin coating of paint, though, of course, there would be some {LCCllHlllltLtlOIl at the ends of the case.

The construction of Fig. d difl'ersfrom that in Figs. 2 and 3, in that the rail-engaging strap 4 passes through both layers or walls of the lower doubled back end 2 instead of through a single wall or layer. as shown in Figs. :2 and 3. Figs. 5, 6 and 7 are the same as tha shown in Figs. 1, 2 and 3, so far as the construction of the inner and outer cases'6 and 1 are concerned, and difl'er only in that the strap 4 passes through openings 8, which are arranged in the outer doubled back end 6 formed from tubes previously constructedand flattened, yet I desire it to be understood that the inner tube or explosive container 1 may be formed from a sheet wrapped around the explosive which, of course, forms a tube and that the outer case 6 can also be made from a sheet wrapped around the inner case, but in these two in stances the inner and outer cases are composed of flattened tubes and do not differ in construction from that here shown, one having the tubes formed and flattened before the parts are assembled, while in the other the inner tube is formed by wrapping the sheet around the explosive and the outer tube is formed by wrapping the sheet around the inner tube. in cemented while it is wrapped. The tubes composing the inner and outer cases are formed of several layers of paper which is always the case with paper tubes, and they are formed from a sheet of material whether formed before being assembled or formed as they are being assembled.

Having thus described my invention. what I claim and desire to secure by Letters Patent is: I V V 1. An improved fiber torpedo comprising an inner explosive containing case com posed of a flattened fiber tube having its Of course, the sheet ends extending beyond the explosive and doubled back on the body of the case, the extended ends being of-a length to overlap each other, and an outer fiber case composed of a flattened tube inclosingthe inner explosive containing case and holding its doubled back ends in folded positions, and

a rail-engaging strap.

2. An improved fiber torpedo comprising an inner explosive containing case composed of a flattened fiber tube having its ends extending beyond the explosive and flattened and doubled back under thebody of the case, and a rail-engaging strapfattached to the outer doubled back flattened ends, and an outer inclosing case composed of a flattened tube receiving the inner case and holding the doubledback ends in their folded position and inclosing the center of the rail-engaging strap. 7

3. An improved fiber torpedo comprising an inner explosive containing case composed of a flattened fiber tube having its ends extending beyond the explosive and flattened and doubled back on the bottom of the'case, the outer folded end having openings, a rail-engaging strap passing through the said openings, and an outer inclosing case composed of a flattened tube inclosing the inner case and the center of the rail en-' gaging strap to hold the extended ends in their folded positions. V

4-. An improved fiber torpedo comprising an inner explosive containing case composed of a flattened fiber tube having its ends extending beyond the explosive and flattened and doubled back under the body housing the folded tube.

In testimony whereof I hereunto my signature 1n the presence of two witnesses.
